WRENCH.

Specification of Letters Patent.

Patented Dec. 31, 1907.

Application filed March 30,1907. Serial No. 365.558.

To all whom it may concern:

Be it known that I, MILTON CLEVEN- STINE, a citizen of the UnitedStates, residing at Kimberton, in the county of Chester and State ofPennsylvania, have invented new and useful Improvements in *vVrenches,of which the following is a specification.

This invention relates to wrenches and more particularly to ratchetwrenches, the object being to provide a ratchet wrench which can beoperated in either direction so as to screw up a nut or unscrew thesame.

Another object of my invention is to provide very novel means forlocking the pawls out of engagement with the ratchet wheels.

Another object of my invention is to provide the ratchet wheels with anadjustable jaw so that they can be adjusted to suit different size nuts.

lVith these and other objects in view, the invention consists in thenovel features of construction, combination and arrangement of partshereinafter fully described and point ed out in the claims.

In the drawing forming a part of this specification: Figure 1' is abottom plan view of my improved wrench. Fig. 2 is a side elevationalview of the same. Fig. 3 is a section. taken on lines 3 3 of Fig. 1.Fig. 4 is a detail sectional view showing the pawl In the drawing Aindicates a handle provided with an offset arm A at one end, having anaperture A in its end, in which is loosely mounted a machine bolt B,extending out centrally from a pair of oppositely toothed ratchet wheels0 and D, which are secured together by machine-screws E.

Secured on the outer face of the wheel D is a rectangular shaped jaw F,provided with apertured ears F, through which screws pass and securelylock the jaw on the wheels.

The side walls of the frame are beveled in which is slidably mounted awedge-shaped jaw G, provided with a sleeve G in which is swiveled thehead of a thumb-screw H, which is mounted in a threaded boss F in oneend, of the frame, so as to adjust the jaw to suit different size nuts.

Spaced bores J and K are formed in the end of the handle communicatingwith bayonet-slots J, K formed on the top of the handle and with slotsformed in the side of the handle. Coiled springs L are arranged in thebores which bear against the ends of pawls M N slidably mounted in thebores having threaded openings adjacent their ends, in which are securedpins M, N which extend out through the bayonet-slots and are providedwith heads at their ends, so that they can be readily operated in theslots with the finger. The ends of the pawls are oppositely beveled soas to fit in between the teeth and slide over the respective ratchetwheels.

It will be readily seen that either of the pawls can be drawn out ofengagement with the respective ratchet-wheels, and locked so that thewrench can be used for turning a nut in any direction desired.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent is 1. In a wrench, the combination with ahandle, provided with an offset arm at one end, of a pair of oppositelytoothed ratchet wheels secured together loosely mounted 011 the end ofsaid arm, a jaw secured on the face of the outer ratchet wheel andspring actuated pawls mounted in the ends of the handle carrying pinsworking in bayonetslots formedin the handle.

2. The combination with a handle, provided with spaced bores at one end,communicating with bayonet-slots formed in the handle, of an offset armeXtending out from said. end, oppositely toothed ratchet-wheels mounted.on the end of the said arm, an adjustable jaw secured on the face of theouter ratchet wheel, spring actuated pawls mounted in said. bores, andpins carried by said pawls working in said bayonet-slots.
